Abstract
The uptake and accumulation of lead, nickel, cadmium, chromium and arsenic in
the root, stem leaves and fruits of okra (Ablmoschus esculentus) and pepper
(Capsicum annum), and the leaves and root of lettuce (Lactuca sativa) at different
metal concentrations in the soil was studied. The physio-chemical properties of the
soil indicate: total nitrogen as 0.21%, organic matter 3.32%, cation exchange
capacity (CEC) was 17.20 mol/kg, clay 20%, silt 46% and sand 34%. The soil pH
was weakly acidic and the textural class was loam. The result obtained for uptake
and accumulation showed that different plants had different preferences for each
metal at the concentration used. The variation in the concentration of applied metal
ion increased.
